IdealPhotonics' high-power fiber Bragg grating is a damage-resistant grating device specifically designed for high-energy laser systems. Through a special cladding mode stripping structure (loss <0.02dB/m) and large mode field fiber writing technology (intensity threshold >1GW/cm²), it achieves stable 10,000-watt laser output with high reflectivity (>99%), suitable for constructing resonant cavities in industrial fiber laser cutting/welding.The "megawatt-level grating armor," through ytterbium-doped cladding design (heat-resistant power >5kW) and ultraviolet ultrashort pulse writing (damage threshold >2GW/cm²), achieves long-term stability of 10kW-level lasers (wavelength drift <5pm/1000h) while maintaining high reflectivity (>99.5%), becoming a "power valve" for 10,000-watt fiber laser resonant cavities.
